If the Most Interesting Man in the World were not some ad-man's construct, I'd nominate Peter Freuchen...
except he died in 1957, and I imagine that would disqualify him.

Big dude.

Standing six feet seven inches, Freuchen was an arctic explorer, journalist, author, and anthropologist.
He participated in several arctic journeys (including a 1000-mile dogsled trip across Greenland),
starred in an Oscar-winning film, wrote more than a dozen books (novels and nonfiction, including his
Famous Book of the Eskimos), had a peg leg (he lost his leg to frostbite in 1926; he amputated his
gangrenous toes himself), was involved in the Danish resistance against Germany, was imprisoned
and sentenced to death by the Nazis before escaping to Sweden, studied to be a doctor at university,
his first wife was Inuit and his second was a Danish margarine heiress, became friends with Jean Harlow
and Mae West, once escaped from a blizzard shelter by cutting his way out of it with a knife fashioned
from his own feces, and, last but certainly not least, won $64,000 on The $64,000 Question.
